Definitions

  • the present invention relates to a method for planning an optimized tillage process according to the preamble of claim 1 and a planning control arrangement according to claim 18.
  • Agricultural machines such as combine harvesters, forage harvesters and tractors can be combined with various attachments. These attachments are attached to the agricultural working machine via a device interface. In the present case, agricultural teams with an agricultural working machine and an agricultural attachment are in the foreground. This is preferably pulled by the agricultural machine.
  • Such attachments are generally used to carry out an agricultural work task.
  • the focus here is on tillage such as plowing or cultivating. What these tillages have in common is that the attachments are usually set to a specific working depth.
  • the success and energy consumption of tillage often depend significantly on the working depth. At the same time, however, this depends on various machine parameters of the attachment and the agricultural working machine.
  • the working depth is usually set at the start of tillage, even manually, depending on the attachment. This setting is often based on the experience of the user and not on the basis of objective criteria. Furthermore, the working depth is often not adjusted during the tillage process. However, this neglects the fact that machine parameters of the agricultural working machine also have an influence on the working depth. For example, a rear power lift can lift a plow or adjust its working depth. These changes are not transparent to the user, are often made dependent on control parameters such as a missing amount of draft and are not tuned to the tillage process.
  • sensors for determining an absolute working depth are possible in principle, they are relatively expensive.
  • a farm often has various agricultural attachments, all of which would benefit from determining a working height.
  • the working depth is regarded as a special case of the working height.
  • the working depth is a working height that protrudes into the ground.
  • the attachments cannot all be fitted with a sensor to determine the working height.
  • the absolute working depth of tillage attachments is usually not determined in practice.
  • the invention is based on the problem of designing and developing the known methods in such a way that a solution for improved soil cultivation is created that achieves an improvement in the disadvantages mentioned and can be used cost-effectively at the same time.
  • recommendations for action for a tillage process can be generated by means of a planning and control arrangement. These recommendations for action are determined from a model, in particular an expert model. Specific recommendations for action can be determined by taking into account the location-dependent soil data of a field. Location-dependent are soil data that change over a field and map data accordingly depending on a position on the field for different positions on the field.
  • a method for planning an optimized tillage process of a field for an agricultural team the agricultural team having an agricultural working machine and a soil-working agricultural attachment, wherein a planning control arrangement is provided, the planning control arrangement using a model, in particular an expert model , recommendations for action for the tillage process are determined from soil data of the field, with the soil data of the field being location-dependent.
  • a recommendation for action can relate to the question of what type of tillage should be carried out.
  • the effect that can be had by selecting optimized tillages on the cost or effectiveness side is large compared to the effect of changes in tillage implementation itself.
  • This decision is made by taking a holistic view of the field based on the location-dependent soil data. For reasons of efficiency, sub-optimal solutions for individual field areas can also be considered if, for example, one type of tillage is completely avoided.
  • a single sensor can be used to determine the working height of various agricultural attachments.
  • This sensor can be attached to a mounting position on the agricultural working machine or the attachments. Thanks to reuse, a separate sensor does not have to be purchased for each attachment, but it becomes possible to support various work processes.
  • the focus here is on using such a sensor for tillage, whereby the installation position is calculated from the measurement data or an optimized working depth is determined depending on the installation position. This enables a cost-effective optimization of tillage, which in particular also Possibility to regulate the absolute working depth based on the measurement data of the sensor in the field depending on the location. As a result, the entire field no longer has to be tilled with a single working depth that may change in an uncontrolled manner. Rather, it is possible to plan and carry out soil cultivation in an optimized manner.
  • a modular sensor system in which the sensor can be mounted reversibly on the attachments and is used to determine the working height of several attachments.
  • the sensor can be designed as a distance sensor.
  • Claim 6 specifies preferred types of distance sensors. These have proven particularly useful in the agricultural sector. In particular, they offer a good balance between robustness and cost.
  • Claims 7 to 12 specify ground data that are preferably taken into account by the planning control arrangement.
  • Claim 7 specifies general ground data that provide information about the general condition, in particular of the entire field.
  • the location-dependent soil data can include lane data in particular, which primarily indicate how much the soil of the field was compacted in a lane. It can thus be taken into account that the condition of the ground within the lanes can deviate significantly from the condition of the ground outside of the lanes.
  • the location-dependent soil data according to claim 9 can include work process data on past soil tillage processes and/or past crop tillage processes.
  • a field is primarily characterized by its use and processing. Different crop rotations, different tillages and the like change the condition of the field and the condition of the soil. For example, root properties of the field, fertilization processes and naturally invasive soil cultivation such as plowing are relevant.
  • the work process data include harvest data from past harvest periods. These can be used to approximate unknown influences and properties of the field.
  • environmental data can also be contained in the ground data. These can relate to a soil type and/or a soil condition. They can be determined in particular by laboratory analyzes of soil samples. Fertilization processes and the weather also have an influence on the soil condition.
  • image data and/or satellite data of the field can be used in order to obtain and take into account biomass data and weed data, for example.
  • This embodiment is the subject of claim 12.
  • the planning control arrangement can also take into account the existing machine park consisting of existing agricultural working machines and attachments by means of the model. Different working machines and attachments have different influences on the ground, can realistically perform different working depths and, if necessary, several fields have to be cultivated at the same time, so that the machinery has to be distributed accordingly.
  • the model can also be used to optimize other attachment settings.
  • This configuration is the subject of claim 14.
  • a cutting width of a plow is relevant. In this way, all parameters of tillage can be coordinated with one another.
  • the planning control arrangement proposes an optimized selection of possible sensors and mounting positions by means of the model.
  • the sensors can be distributed to those work processes where deviations in working height or working depth have the greatest impact in order to achieve an optimized result with limited resources.
  • An advantage of the sensor arrangement and the reuse of the sensor is that, as proposed according to claim 16, measured values from past tillage processes can be used as soil data.
  • tillage may be targeted for maximum speed or maximum fuel efficiency. Neither possibility is, as such, necessarily the right one. For example, if tillage needs to be completed before the weather changes, speed can be prioritized. This embodiment is the subject of claim 17.
  • a planning control arrangement is set up for use in the proposed method.
  • the agricultural working machine 1 is a tractor.
  • the working machine 1 can be equipped with at least one attachment 3 via at least one device interface 2 .
  • the device interface 2 is here quite generally a mechanical coupling between the work machine 1 and the attachment 3.
  • the device interface 2 is designed as a three-point power lift which has two lower links for coupling to the attachment 3 and has a top link.
  • the device interface 2 can be designed as a front or rear power lift. In principle, however, the device interface 2 can also be a drawbar.
  • Other variants for the device interface 2 are systems with a simple drawbar coupling, with a hitch hook, with a ball head coupling or the like.
  • the soil-working attachment 3 is preferably a private vehicle.
  • the exemplary embodiment illustrated in the figures and preferred in this respect relates to a method for planning an optimized tillage process of a field for an agricultural vehicle 4.
  • the agricultural vehicle combination 4 has an agricultural working machine 1 and an agricultural attachment 3 that tills the soil.
  • the attachment 3 can be a plow 5, a cultivator and the like.
  • a sensor arrangement 6 to be explained is provided for determining an absolute working depth 7 of the agricultural attachment 3 .
  • the sensor arrangement 6 has a sensor 8 for determining measurement data relating to an absolute working depth 7 of the attachment 3 , a sensor holder 9 and a sensor control arrangement 10 .
  • the sensor 8 When mounted at a mounting position 11, the sensor 8 records measurement data relating to an absolute working depth 7 of the attachment 3 during the tillage process and transmits this to the sensor control arrangement 10.
  • the sensor arrangement 6 can be independent or at least partially integrated into the agricultural working machine 1 .
  • the sensor control arrangement 10 of the sensor arrangement 6 can be a control arrangement of the agricultural working machine 1, for example. Equally, however, this can also consist of distributed computing units. For example, it can have a control unit of the agricultural working machine 1 and a cloud control unit.
  • An absolute working depth 7 is measured by means of the sensor 8 .
  • the term "absolute” does not necessarily mean a highly accurate measurement, but generally a measurement relative to the floor 12. It is fundamentally conceivable that the measurement takes place relative to a component whose height or depth relative to the floor 12 is in turn known, however, the absolute working depth 7 is preferably measured directly relative to the ground 12 .
  • a planning control arrangement 13 which uses a model, in particular Expert model, recommendations for action for the tillage process determined from soil data of the field.
  • location-dependent is to be understood as meaning that the ground data change over a field and accordingly still have a spatial resolution on the individual field.
  • location-dependent soil data to determine recommendations for action for tillage enables recommendations for action that are optimized for the field as a whole.
  • the recommended action is aimed at a user who can accept, reject or change it based on his or her experience.
  • the final decision is therefore up to the user.
  • the recommendations for action can include a type of tillage, preferably a recommendation as to whether tillage should include cultivating and/or plowing.
  • a type of tillage preferably a recommendation as to whether tillage should include cultivating and/or plowing.
  • the decision on the type of tillage is made by the user based on experience and/or habit.
  • the optimization of this decision by means of the planning control arrangement 13 and thus based on objective criteria that are stored in the model leads to a possible optimization, in particular by omitting individual types of tillage, which can generate significant cost savings.
  • the recommendations for action include a type of tillage and tillage parameters, in particular a working depth 7 .
  • a type of tillage and tillage parameters in particular a working depth 7 .
  • the planning control arrangement 13 uses the model, in particular an expert model, to determine an optimized absolute working depth 7 of the attachment 3 for the soil cultivation process from the soil data.

  • the assembly position 11 can be arranged on the attachment 3 or the agricultural working machine 1 . It can be fixed or variable.
  • the mounting position 11 is preferably adapted to the work process, as will be explained in the context of the modular sensor system. In the same way, however, the sensor 8 can also remain fixed on the agricultural working machine 1 .
  • the model is an expert model that can optionally be expanded to include field-specific feedback.
  • other types of models are just as conceivable. In particular, it is conceivable to train an AI model from the soil data and yield data mentioned.
  • the setting of the working depth 7 by means of the trailer control arrangement 14 does not have to be comprehensive.

  • the assembly position 11 is located here and preferably on the tillage attachment 3.
  • 2 shows schematically how, for example, a longitudinal inclination and a transverse inclination can exist in a soil-working attachment, which ensure that the working depth 7 as such is not constant over the plow 5 is. 2 also shows how a number of sensors 8 can be used to determine these inclinations or, in general, a number of working depths 7 .

  • the soil data includes a crop rotation of the field, in particular current crops and/or past crops and/or catch crops and/or planned crops, and/or environmental data, preferably climate data, in particular temperatures and/or amounts of precipitation, and /or soil type data and/or soil condition data.
  • This data can come from a database, from the Internet and/or from the agricultural team 4. They have in common that they mostly concern the entire field. In addition to this general data, ground data can also be provided which very specifically only relate to certain field sections and the like. These will be considered in more detail below.
  • the location-dependent ground data includes lane data.
  • the condition of the ground when driving on may have been determined in a previous plan using the model. It is particularly preferred that the soil condition is determined from data from previous applications of the proposed method.
  • the location-dependent soil data can also be made for the location-dependent soil data to include work process data on past soil tillage processes and/or past crop tillage processes.
  • the work process data preferably includes data on working depths 7 and/or attachments 3 from previous tillage processes and/or data on fertilization and/or plant protection measures and/or sprinkling of previous crop tillage processes.
  • a current soil condition is determined from a past soil condition in combination with a history of soil cultivation processes.
  • the work process data include harvest data from past harvest periods, preferably that the model is adapted based on harvest data from past work processes, in particular depending on the field.
  • the model itself is not adapted to a single field, but can be adapted via feedback, in particular from the harvest data mentioned.
  • This adjustment is done here and preferably automatically. Above all, this takes into account the fact that it is hardly possible to determine all relevant soil properties and influencing parameters. These deviations are taken into account here and preferably by means of a correction factor, which is determined from the harvesting data from previous work processes.
  • the location-dependent soil data to include environmental data, preferably for the environmental data to include soil type data and/or soil condition data, more preferably for the soil type data and/or the soil condition data to be determined at least in part from soil samples and/or to include nutrient data.
  • the location-dependent soil data include satellite data of the field, in particular biomass data determined from satellite data, and/or that the location-dependent soil data include image data of the field, in particular drone image data of the field, preferably that the image data of the field include weed data , especially weed species.
  • the planning control arrangement 13 can use the model to take existing agricultural working machines 1 and/or attachments 3 into account when determining the optimized working depth 7, preferably for the planning control arrangement 13 to use the model to calculate an agricultural working machine 1 and/or a Attachment 3 proposes to carry out the tillage process.
  • Agricultural holdings often have a fleet of agricultural working machines 1 and agricultural attachments 3 . It is then regularly necessary to plan not just one field cultivation process, but several work processes at the same time. The available resources must be divided between these work processes. There may be some work processes that are more dependent on working height 15 or working depth 7 than others. Also, not every working height 15 can be set efficiently on every attachment 3 or with every agricultural working machine 1 . It is therefore advantageous to take these factors into account during planning in order to plan the tillage process in such a way that the working depth 7 can be carried out and is also optimized with regard to other work processes. For this purpose, the planning control arrangement 13 can also propose the working machine 1 and the attachment 3 in addition to the working depth 7 .
  • the planning control arrangement 13 uses the model to determine at least one further optimized setting of the attachment 3, in particular as a function of the working depth 7, preferably that the further optimized setting is a cutting width of a plow 5.
  • a soil cultivation process in particular with a plow 5, is not only influenced by the working depth 7, but also by other machine parameters of the attachment 3, but also by other machine parameters of the attachment 3, such as a cutting width of a plow 5.
  • the planning control arrangement 13 proposes an optimized selection of one or more sensors 8 and/or sensor types and/or mounting positions 11 and/or a sensor number of the sensor arrangement 6 by means of the model.
  • sensors 8 different types are provided.
  • several sensors 8 per attachment 3 can be used at different mounting positions 11 .
  • the sensor placement, number and type can also be optimized accordingly.
  • the sensor data from these different work processes can serve as a basis for the model. It is here and preferably provided that the measurement data are stored and processed in a standardized manner and independent of attachments and/or independent of the mounting position. A type of ground memory can thus be created over a longer period of time by means of the sensor arrangement 6 .
  • the planning control arrangement 13 takes into account competing targets when determining the optimized working depth 7, preferably that the targets minimized fuel consumption and/or maximized speed of implementation of the tillage process and/or minimization of the costs of the tillage process and /or includes maximizing the quality of work.
  • the user 16 can weight the targets and preferably adjust that weighting visually. This weighting can be entered and taken into account both when planning the tillage process and during implementation. However, the focus here is on planning.
  • a planning control arrangement 13 is also proposed for use in the proposed method.
